OPEN PHIGS

POPPH

CALL SEQUENCE

CALL POPPH (ERRFIL, BUFA)

INPUT PARAMETERS

INTEGER ERRFIL

Error message file.

INTEGER BUFA

Memory required by the application. This argument is not used by GPHIGS. GPHIGS automatically sets aside the amount of memory it requires.

PHIGS STATE

EFFECT

Opens GPHIGS, allocating and initializing the PHIGS data structures. The PHIGS and workstation description tables and state lists become accessible using the inquire functions. The PHIGS STATE list entry error file is set to ERRFIL and the system state is set to PHOP.

OPEN PHIGS must be called before any other PHIGS functions are called.

In GPHIGS, BUFA is unused.

EXTENSION TO THE PHIGS STANDARD

GPHIGS allows programmers to define a set of parameters, used by GPHIGS, that are not provided into the PHIGS standard (window size, double buffering). See the extension function SET CONFIGURATION FILE NAME for more details on these parameters.
